JAR,

SPECIFICATION forming part of Letters Patent No. 228,938, dated June 15, 1880.

Application filed April 26, 1880.

To all whom it may concern:

Be it known that I, NELSON ROGERS, of Elgin, in the county of Kane and State ofIllinois, have invented a new and useful Improvement in Jars; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being bad to the accompanying drawings, forming part of this specification, in which Figure 1 is a side view, partly in section, of my invention as embodied in a fruit-jar. Fig. 2 is a sectionalview of the invention as embodied in a butter-package. Fig. 3 is a perspective view of the glass cover. Fig. 4 is a section of the same through the line as wot Fig. 3. Fig. 5 is a plan view of the packing-ring.

My invention relates to certain improvements in jars of that class which are employed for holding fruits, vegetables, butter, milk, 850., and which are designed to be hermetically sealed. It is an improvement in that general form of jar in which a glass cover is made to rest inside the neck of the jar upon a shoulder, and the joint made tight by an elastic ring and a screw-cap.

My improvement consists, mainly, in forming the glass cover with a recess about its upper edge, placing therein a ring of cork or other elastic material, and then fastening an angular annular screw cap over the flush edges of the glass cover, the elastic ring, and the edge of the jar, so as to hold the parts to their places and make a tight joint, as hereinafter more fully described.

Referring to the drawings, A represents the jar; B, the glass cover; 0, the ring, of cork, rubber, or other analogous material; and D, the annular screw-cap.

In constructing the jar its neck portion or inner edge is made of a slightly larger internal diameter, and has a shoulder, (0, upon which rests the edges of the glass cover, the

external periphery, b, of the glass cover fitting also flush up against the inner wall of the jar. The upper edge of the glass cover is recessed or rabbeted, and into the same is placed a ring, 0, of cork, rubber, or other elastic material. I prefer cork, however, for the reason that the nature of my invention permits it to be used, and it has the advantage of being taste- (No model.)

less, and undergoes no change from lapse of time. Theouter face of thiscork ring is slightly tapering, so as to cause it to enter the neck with a wedging action to make a tight joint, and its upper surface is about flush with the top surface of the glass cover and the edge of the jar, which permits the top section, 01, of the screw-cap D to fit closely down upon the top of the vessel, while the side section, 0, which is formed with a screw, laps down on the outside of the jar and engages with the thread formed thereon.

Now, in defining my invention with greater clearness, I would state that I am aware that much has been done in the line of fruit-jars, and most of the elements of my combination are old when separately regarded. Thus, for instance, it is not new to increase the size of the neck of the jar and form a shoulder, a, upon which a glass cover is seated, and then to pack the joint with an elastic ring, as shown in Patents Nos. 96,869 and 98,586. It is also old to employ a screw-cap for fastening the cover down upon the jar. I therefore do not I claim these features separately.

The distinguishing features of my invention are to be found in making the upper surface of the glass cover and the upper edge of the jar about level with each other and forming on the upper edge of the glass cover a recess, which receives the elastic ring, so that its outer surface may be flush, and then fastening the cover and packing-ring down by a right-angular screw-cap, which fits flatly down upon the edge of the cover, the packing-ring, and edge of the jar, and extends also down upon the outside of the jar.

Incidental to this arrangement are the following advantages: The contents of the jar are not allowed to come in contact with the elastic ring, being separated therefrom by the joints to and b, and confined wholly to glass surfaces, while the elastic ring serves to prevent any leakage that may take place through the joints a and b.

This general result has in a measure been heretofore attained, but not in so practical a manner.

The distinctive result of my invention is to be found in preserving the aforesaid advantage IOO of a tight joint with an external packingring, and at the same time securing a compact fastening and a strongly re-enforced edge by making the screw-cap D to tit down fiat on the top of the jar, which is permitted by recessing the top edge of the glass cover. This peculiarity may be found advantageous for other reasons. Thus, for instance, when theinvention is embodied in the form of a butter jar or package, the elastic ring may be left off, and in this case, after filling thejar with butter, the annular cavity left by the packingring may be filled with brine, and the screwcap then screwed down, a piece of cloth or other equivalent material being laid over the cover, if desired, to cause the screw-cap to tightly retain the brine.

Having thus described my invention, What I claim as new is-- The combination, with a jar having a shoulder at a and screw-threaded on the outer edge, of the glass cover formed with a recess in its upper edge and having its upper side flush with the edge of the jar, together with an elastic packing-ring located in said recess, and an annular screwcap lapping flatly upon the flush edges of the cover, elastic ring, and edge of the jar, and extending down upon the outside of the jar, substantially as described.

NELSON ROGERS.
